These settings are available in system.settings and are autogenerated from source.

​
send_profile_events

Enables or disables sending of ProfileEvents packets to the client. This can be disabled to reduce network traffic for clients that do not require profile events. Possible values:
  • 0 — Disabled.
  • 1 — Enabled.

​
send_progress_in_http_headers

Enables or disables X-ClickHouse-Progress HTTP response headers in clickhouse-server responses. For more information, read the HTTP interface description. Possible values:
  • 0 — Disabled.
  • 1 — Enabled.

​
send_table_structure_on_insert_with_inline_data

If disabled and the INSERT query contains inline data, the server will not send the table structure and column defaults back to the client over the native protocol. Instead, the server will parse the inline data itself. This can improve performance for many small inserts over the native protocol.

​
send_timeout

Timeout for sending data to the network, in seconds. If a client needs to send some data but is not able to send any bytes in this interval, the exception is thrown. If you set this setting on the client, the ‘receive_timeout’ for the socket will also be set on the corresponding connection end on the server.
